Coalition-structured governance improves cooperation to provide public goods

Area of Science:

• Environmental Science
• Game Theory
• Political Science

Background:

• Voluntary contributions to public goods often lead to scarcity due to free-riding.
• Cooperative dilemmas are central to sustainability challenges, from local resources to global climate change.
• Real-world cooperation involves complex strategies and incomplete information.

Purpose of the Study:

• To investigate the effectiveness of multi-coalition governance in overcoming public goods dilemmas.
• To demonstrate the generalizability and robustness of polycentricity in fostering cooperation.
• To compare cooperation levels between single and multi-coalition governance structures.

Main Methods:

• Theoretical modeling of public goods provision under different governance structures.
• Analysis of voluntary cooperation with self-interested players and varying return-to-contribution functions.
• Comparison of cooperative outcomes in single-coalition versus multi-coalition (polycentric) systems.

Main Results:

• A single coalition without enforcement is prone to cooperative failure.
• Multi-coalition governance significantly increases cooperation by highlighting marginal gains.
• Polycentric systems outperform singular regimes in maintaining and increasing cooperation, even without enforcement.

Conclusions:

• Polycentric governance, characterized by overlapping coalitions, enhances the generation of public goods.
• This multi-coalition approach promotes more cooperative, stable, and inclusive governance outcomes.
• Voluntary cooperative forums can successfully sustain cooperation in the absence of formal enforcement mechanisms.
